Submitting some enhancements

[TaylorPhelps]

Refactoring getProperty method: refactored the getProperty method to handle default values more efficiently and avoid redundant code.

Corrected initialization of static fields: ensured that the static fields in the Config class are initialized properly by reading values from the build.template.properties file.

Handled environment-specific properties: The Config class now handles properties differently based on whether the application is running in a development environment (dev.properties) or a production environment (build.properties).

Fixed logging: ensured that the application logs meaningful information during startup, such as the instance ID, zone rules version, and server startup messages. This helps in monitoring and debugging the application.
